Pharmacology

Paclitaxel is a taxoid antineoplastic agent indicated as first-line and subsequent therapy for the treatment of advanced carcinoma of the ovary, and other various cancers including breast cancer. Paclitaxel is a novel antimicrotubule agent that promotes the assembly of microtubules from tubulin dimers and stabilizes microtubules by preventing depolymerization. This stability results in the inhibition of the normal dynamic reorganization of the microtubule network that is essential for vital interphase and mitotic cellular functions. In addition, paclitaxel induces abnormal arrays or "bundles" of microtubules throughout the cell cycle and multiple asters of microtubules during mitosis.

Patient Information

TAXOL®INJECTION

(generic name = paclitaxel)

WHAT IS TAXOL?

TAXOL is a prescription cancer medicine. It is injected into a vein and it is used to treat different
types of tumors. The tumors include advanced ovary and breast cancer. The tumors also include certain lung cancers
(non-small cell) in people who cannot have surgery or radiation therapy. TAXOL may also be used to treat AIDS-related
Kaposi’s sarcoma.

WHAT IS CANCER?

Under normal conditions, the cells in your body divide and grow in an orderly, controlled way. Cell
division and growth are necessary for the human body to perform its functions and to repair itself, when necessary.
Cancer cells are different from normal cells because they are not able to control their own growth. The reasons for
this abnormal growth are not yet fully understood.

A tumor is a mass of unhealthy cells that are dividing and growing fast and in an uncontrolled way.
When a tumor invades surrounding healthy body tissue it is known as a malignant tumor. A malignant tumor can spread
(metastasize) from its original site to other parts of the body if not found and treated early.

HOW DOES TAXOL WORK?

TAXOL is a type of medical treatment called chemotherapy. The purpose of chemotherapy is to kill
cancer cells or prevent their growth.

All cells, whether they are healthy cells or cancer cells, go through several stages of growth. During
one of the stages, the cell starts to divide. TAXOL may stop the cells from dividing and growing, so they eventually
die. In addition, normal cells may also be affected by TAXOL causing some of the side effects.

WHO SHOULD NOT TAKE TAXOL?

Patients who have a history of hypersensitivity (allergic reactions) to TAXOL or other drugs
containing Cremophor® EL* (polyoxyethylated castor oil), like cyclosporine or teniposide, should not
be given TAXOL. In addition, TAXOL should not be given to patients with dangerously low white blood cell counts.

HOW IS TAXOL (PACLITAXEL) INJECTION GIVEN?

TAXOL is injected into a vein [intravenous (I.V.) infusion]. Before you are given TAXOL, you will have
to take certain medicines (premedications) to prevent or reduce the chance you will have a serious allergic reaction.
Such reactions have occurred in a small number of patients while receiving TAXOL and have been rarely fatal..

WHAT ARE THE POSSIBLE SIDE EFFECTS OF TAXOL?

Most patients taking TAXOL will experience side effects, although it is not always possible to tell
whether such effects are caused by TAXOL, another medicine they may be taking, or the cancer itself. Important side
effects are described below; however, some patients may experience other side effects that are less common. Report
any unusual symptoms to your doctor.

Important side effects observed in studies of patients taking TAXOL were as follows:

– Allergic reactions. Allergic reactions can vary in degrees of severity. They may cause death in
rare cases. When a severe allergic reaction develops, it usually occurs at the time the medicine is entering the
body (during TAXOL infusion). Allergic reactions may cause trouble breathing, very low blood pressure, sudden
swelling, and/or hives or rash. The likelihood of a serious allergic reaction is lowered by the use of several
kinds of medicines that are given to you before the TAXOL (paclitaxel) Injection infusion.

– Heart and blood vessel (cardiovascular) effects. TAXOL may cause a drop in heart rate
(bradycardia) and low blood pressure (hypotension). The patient usually does not notice these changes. These
changes usually do not require treatment. Your heart function, including blood pressure and pulse, will be
monitored while you are receiving the medicine. You should notify your doctor if you have a history of heart
disease.

– Infections due to low white blood cell count. Among the body’s defenses against bacterial
infections are white blood cells. Between your TAXOL treatment cycles, you will often have blood tests to check
your white blood cell counts. TAXOL usually causes a brief drop in white blood cells. If you have a fever
(temperature above 100.4° F) or other sign of infection, tell your doctor right away. Sometimes serious
infections develop that require treatment in the hospital with antibiotics. Serious illness or death could result
if such infections are not treated when white blood cell counts are low.

– Hair loss. Complete hair loss, or alopecia, almost always occurs with TAXOL. This usually
involves the loss of eyebrows, eyelashes, and pubic hair, as well as scalp hair. It can occur suddenly after
treatment has begun, but usually happens 14 to 21 days after treatment. Hair generally grows back after
you’ve finished your TAXOL treatment.

– Joint and muscle pain. You may get joint and muscle pain a few days after your TAXOL treatment.
These symptoms usually disappear in a few days. Although pain medicine may not be necessary, tell your doctor if
you are uncomfortable.

– Irritation at the injection site. TAXOL sometimes causes irritation at the site where it enters
the vein. Reactions may include discomfort, redness, swelling, inflammation (of the surrounding skin or of the vein
itself), and ulceration (open sores). These reactions are usually caused by the I.V. (intravenous) fluid leaking
into the surrounding area. If you notice anything unusual at the site of the injection (needle), either during
or after treatment, tell your doctor right away.

– Low red blood cell count. Red blood cells deliver oxygen to tissues throughout all parts of the
body and take carbon dioxide from the tissues by using a protein called hemoglobin. A lowering of the volume of red
blood cells may occur following TAXOL treatment causing anemia. Some patients may need a blood transfusion to treat
the anemia. Patients can feel tired, tire easily, appear pale, and become short of breath. Contact your doctor if
you experience any of these symptoms following TAXOL treatment.

– Mouth or lip sores (mucositis). Some patients develop redness and/or sores in the mouth or on the
lips. These symptoms might occur a few days after the TAXOL treatment and usually decrease or disappear within one
week. Talk with your doctor about proper mouth care and other ways to prevent or reduce your chances of developing
mucositis.

These symptoms occur often with TAXOL and usually get better or go away without medication within several months
of completing treatment. However, if you are uncomfortable, tell your doctor so that he/she can decide the best
approach for relief of your symptoms.

– Stomach upset and diarrhea. Some patients experience nausea, vomiting, and/or diarrhea following
TAXOL use. If you experience nausea or stomach upset, tell your doctor. Diarrhea will usually disappear without
treatment; however, if you experience severe abdominal or stomach area pain and/or severe
diarrhea, tell your doctor right away.

Talk with your doctor or other healthcare professional to discuss ways to prevent or reduce some of
these side effects. Because this leaflet does not include all possible side effects that can occur with TAXOL, it is
important to talk with your doctor about other possible side effects.

CAN I TAKE TAXOL IF I AM PREGNANT OR NURSING A BABY?

TAXOLcould harm the fetus when given to a pregnant woman. Women should avoid becoming pregnant while
they are undergoing treatment with TAXOL.

Tell your doctor if you become pregnant or plan to become pregnant while taking TAXOL.

Because studies have shown TAXOL to be present in the breast milk of animals receiving the drug, it
may be present in human breast milk as well. Therefore, nursing a baby while taking TAXOL is NOT recommended.
